Hi thanks for contacting HCM... According to your history here it doesn t seems to be serious condition... It might be simple musculoskeletal pain or by costochondritis like condition.. Costochondritis is inflammation of costal cartilages.... Ibuprofen like drug given for it.... Meanwhile if you excessively travel then also it can occur... Take proper posture while sleeping.... Avoid strenous work .... Hope your concern solved. You can consult physician for examination ...as physical examination needed with clinical history for proper diagnosis. Take care.
